Lindsay Lohan is no stranger to nudity — she famously stripped for a New York Magazine pictorial last year and appeared half-nude on the cover of Entertainment Weekly in 2004 — but her latest exposure has come via her personal Twitter. Lohan snapped a topless pic of herself using her BlackBerry, with most of her torso covered by her long locks.

"OLD PHOTOS," she wrote. "I'm THAT bored."

Lohan took the shot while on the set of a photo shoot for Fornarina, an Italian fashion label. Lately she's been in the news mostly for her ongoing on/off relationship with Samantha Ronson, though in the past several months has rolled out a line of leggings and appeared in a video on FunnyOrDie.com where she poked fun at her breakup.
